Stock Screening with Volatility, Recent Gains, and MACD Filters

Summary

This Chinese-language post outlines a stock screen combining price movement, recent strength, and MACD. The initial criteria look for stocks with a large daily high-low range, at least one session with a gain of 10% or more in the recent 25 trading days, and MACD above zero. The author describes this as a possible fit for short- to medium-term trading, while noting that it focuses on recent technical conditions and may miss longer-term business prospects or select overbought rebounds.

A proposed expanded screen adds a positive MACD histogram condition relative to its recent average, plus valuation thresholds for price-to-earnings, price-to-book, price-to-sales, and PEG. The post includes example formulas and Python snippets, though the snippets express some filters differently from the prose. It offers no backtest, performance figures, or evidence that the proposed changes improve results. The screen is therefore a set of candidate rules, with suggested additions such as other indicators and risk measures rather than a validated strategy.

Key ideas

• The initial screen combines a large daily price range with a strong gain within the recent 25 trading days.
• It requires MACD to be above zero as a trend filter.
• The expanded proposal adds a MACD histogram condition and valuation limits.
• The author warns that recent technical filters can miss long-term prospects and may select overbought rebounds.
• No backtest or performance evidence is provided.
